Title: BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for Hydraulic Brake Booster): C1381;
Acceleration Sensor Power Supply Voltage Malfunction; 2016 MY Tacoma [08/2015 - ]
DTC C1381 Acceleration Sensor Power Supply Voltage Malfunction
DESCRIPTION
The skid control ECU (master cylinder solenoid) receives signals from the yaw rate and acceleration (airbag
sensor assembly) via the CAN communication system.
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition
using 2 circuits (GL1, GL2).
If there is trouble in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) and the
CAN communication system, DTCs U0123 (yaw rate sensor communication trouble) and U0124 (acceleration
sensor communication trouble) are stored.
These DTCs are also output when calibration has not been completed.
